Changes in Trypanosoma cruzi infectivity by treatments that affect calcium ion levels.

Abstract

The possible role of the intracellular Ca2+ level in the regulation of Trypanosoma cruzi infectivity was explored by measuring the capacity of trypomastigote forms of this organism to invade mammalian host cells after treatments which decrease or elevate cytoplasmic Ca2+. Parasites loaded with either bis-(o-aminophenoxy)-ethane-N,N,N',N' tetraacetic acid… (More)
